Ha. I've been thinking about these sorts of problems and I'm leaning towards the idea that while governments are legitimate (groups of people pooling resources to achieve communal goals with some degree of compromise) most citizens are not legitimate (for lack of a better word). I was born in the US so I get all these rights, benefits, and obligations with no choice. From that viewpoint are immigrants the only "true" citizens of a nation because they actively choose to be a part of it?
